Directories

Introduction

A tiny library with a minimal API (2 structs, 4 factory functions, getters)
that provides the platform-specific, user-accessible locations
for storing configuration, cache and other data
on Linux, Windows (≥ Vista) and macOS.

The library provides the location of these directories by leveraging the mechanisms defined by

the XDG base directory and the XDG user directory specifications on Linux,
the Known Folder system on Windows, and
the Standard Directories on macOS.

Usage

Dependency

Add the library as a dependency to your project by inserting

directories = "0.3.0"

into the [dependencies] section of your Cargo.toml file.

Example

Library run by a user with user name "my_user_name" on Linux:

extern crate directories;
use directories::ProjectDirectories;

let my_proj_dirs = ProjectDirectories.from_project_name("My Project");
my_proj_dirs.project_config_dir; // "/home/my_user_name/.config/my-project/"

Features

`BaseDirectories`

The intended use-case for BaseDirectories is to query the paths of standard directories that have been defined according to the conventions of operating system the library is running on.

If you want to compute the location of cache, config or data directories for your own application or project, use ProjectDirectories instead.

Function name	Value on Linux	Value on Windows	Value on macOS
`home_dir`	`$HOME`	`{FOLDERID_Profile}`	`$HOME`
`cache_dir`	`$XDG_CACHE_DIR` or `~/.cache/`	`{FOLDERID_LocalAppData}/cache/`	`$HOME/Library/Caches/`
`config_dir`	`$XDG_CONFIG_DIR` or `~/.config/`	`{FOLDERID_RoamingAppData}`	`$HOME/Library/Preferences/`
`data_dir`	`$XDG_DATA_DIR` or `~/.local/share/`	`{FOLDERID_LocalAppData}`	`$HOME/Library/Application Support/`
`data_roaming_dir`	`$XDG_DATA_DIR` or `~/.local/share/`	`{FOLDERID_RoamingAppData}`	`$HOME/Library/Application Support/`
`executable_dir`	`Some($XDG_DATA_HOME/../bin/)` or `Some($HOME/.local/bin/)`	`None`	`Some($HOME/Applications/)`
`runtime_dir`	`Some($XDG_RUNTIME_DIR)`	`None`	`None`
`audio_dir`	`XDG_MUSIC_DIR`	`{FOLDERID_Music}`	`$HOME/Music/`
`desktop_dir`	`XDG_DESKTOP_DIR`	`{FOLDERID_Desktop}`	`$HOME/Desktop/`
`document_dir`	`XDG_DOCUMENTS_DIR`	`{FOLDERID_Documents}`	`$HOME/Documents/`
`download_dir`	`XDG_DOWNLOAD_DIR`	`{FOLDERID_Downloads}`	`$HOME/Downloads/`
`font_dir`	`Some($XDG_DATA_HOME/fonts/)` or `Some($HOME/.local/share/fonts/)`	`None`	`Some($HOME/Library/Fonts/)`
`picture_dir`	`XDG_PICTURES_DIR`	`{FOLDERID_Pictures}`	`$HOME/Pictures/`
`public_dir`	`XDG_PUBLICSHARE_DIR`	`{FOLDERID_Public}`	`$HOME/Public/`
`template_dir`	`XDG_TEMPLATES_DIR`	`{FOLDERID_Templates}`	`None`
`video_dir`	`XDG_VIDEOS_DIR`	`{FOLDERID_Videos}`	`$HOME/Movies/`

`ProjectDirectories`

The intended use-case for ProjectDirectories is to compute the location of cache, config or data directories for your own application or project, which are derived from the standard directories.

Function name	Value on Linux	Value on Windows	Value on macOS
`project_cache_dir`	`$XDG_CACHE_DIR/_yourprojectname_` or `$HOME/.cache/_yourprojectname_/`	`{FOLDERID_LocalAppData}/_yourprojectname_/cache/`	`$HOME/Library/Caches/_yourprojectname_/`
`project_config_dir`	`$XDG_CONFIG_DIR/_yourprojectname_` or `$HOME/.config/_yourprojectname_/`	`{FOLDERID_RoamingAppData}/_yourprojectname_/`	`$HOME/Library/Preferences/_yourprojectname_/`
`project_data_dir`	`$XDG_DATA_DIR/_yourprojectname_` or `$HOME/.local/share/_yourprojectname_/`	`{FOLDERID_LocalAppData}/_yourprojectname_/`	`$HOME/Library/Application Support/_yourprojectname_/`
`project_data_roaming_dir`	`$XDG_DATA_DIR/_yourprojectname_` or `$HOME/.local/share/_yourprojectname_/`	`{FOLDERID_RoamingAppData}/_yourprojectname_/`	`$HOME/Library/Application Support/_yourprojectname_/`
`project_runtime_dir`	`Some($XDG_RUNTIME_DIR/_yourprojectname_)` or `Some($HOME/.local/share/_yourprojectname_/)`	`None`	`None`

The specific value of _yourprojectname_ depends on the function used to create the ProjectDirectories struct:

Function name	Example project name	Value on Linux	Value on Windows	Value on macOS
`from_unprocessed_string`	`"FooBar-App"`	`"FooBar-App"`	`"FooBar-App"`	`"FooBar-App"`
`from_project_name`	`"FooBar App"`	`"foobar-app"`	`"FooBar App"`	`"FooBar App"`
`from_qualified_project_name`	`"org.foobar-corp.FooBar-App"`	`"foobar-app"`	`"FooBar-App"`	`"org.foobar-corp.FooBar-App"`

Versioning

After 1.0, the version number of this library consists of a whole number, which is incremented with each release. (Think semantic versioning without minor and patch versions.)
